We were very impressed to find this community-driven open source project, Livetanium, which allows for real-time editing of Titanium source, complete with deployment to the iPhone emulator. The project was pioneered by team krawaller, developers of the Titanium-based word game Golingo (buy it!). Says Jacob Waller:

Made out of titanium, nodejs and unicorns, our Livetanium library lets you code Titanium Mobile apps and see changes in realtime. It uses a nodejs server to pipe filechanges to the app, and these changes are applied in realtime. It’s iPhone only at the moment, but works in both the simulator and on the actual device. You can see a quick walkthrough here or check out the source.

Please try it out and let us know what you think!

Great work guys! You can check out the video they posted by following the link below:
